  • Some devices may have nicotine salt formulations for aerosol delivery. This may deliver a strong head buzz to satisfy nicotine cravings. However, these devices may still deliver nicotine to users, although reducing the harmful byproducts of smoking, but such approaches may help people quit smoking but not quit nicotine. Additionally, unflavored nicotine salt formulations may provide users an artificial/chemical taste, not perceived pleasant or well accepted by users. This may have led to hundreds of added flavors in the e-liquid, many of which contain chemical substances that have not been fully understood regarding their inhalation toxicity and thermal stability. As well, artificially flavored e-liquids have been criticized as being the primary cause of the teen vaping epidemic.
  • Some nicotine liquid formulations for e-cigarette are not nicotine salt based. Such liquid formulations may contain only nicotine freebase.
  • the freebase formulations may fail to provide sufficient satisfaction for nicotine craving at low levels, and they may also be too harsh to inhale when the concentration of nicotine is too high.

  • HPHC harmful and potentially harmful chemicals
  • the level of HPHC released from HnB products may be as low as 5% of what is released from burning cigarettes, it is still higher than e-cigarettes. Nicotine and flavors delivered from tobacco sticks may not be consistent throughout the course of use as it may be heated multiple times until replaced, thus there is no guarantee to release the chemicals from the tobacco sticks evenly from the first puff to the last.
  • non-natural tobacco materials may be used, part of which contains nicotine. Although claimed to achieve cessation of nicotine addiction by using artificial intelligence (AI) to adjust nicotine delivery to users, the device may still use nicotine as the addictive substance. Artificial flavors are likely required to make users more willing to use the products due to the chemical taste of the formulation. [0016] Generally, the use of de-nicotinized combustible cigarettes may still deliver as much of the harmful and potentially harmful chemicals including, e.g., CO, aldehydes, tar, etc., as in normal cigarettes, all of which are the toxins known to be responsible for increasing smokers’ chance of cardio disease and cancers.
